Ball mill is a horizontal grinding mill and key equipment for grinding materials, widely used in ore flotation processing plant and powder-making production line. According to different materials and discharging methods, there are dry ball mills and wet ball mills for choice. Dry ball mill is mainly for producing mineral powder used in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry; Wet ball mill is a kind of continuous ball mill used in ore beneficiation plant. ...Learn More

Magnalium Pyrosource Wiki Fandom Descriptionmagnalium is a very brittle alloy ofmagnesium andaluminum some common uses are in for spark effects in strobing compositions and in crackling stars lancaster gives some typical mesh sizes for different uses magnalium used for strobe stars for spark effects or to enhance other stars has to be finer than 120 mesh while for use incrackling microstars it has to be something Chemicals T Thermite composition industrial in addition because of the particle shape of this fine swarf it burns with a distinctive crackle and it can be easily ball milled to a finer mesh size that is usually not possible with the thicker hammer milled product in a microscope you can see that this swarf is fine machine produced curls
